Hi there! This is my first post on and i hope you forgive my untrained language and other irregularities...

Today, i want to introduce this fancy Longines Dresser to you:


Fast, faster. 36000 A/h

The Longines Movement 431 is beating faster than most in the early 70ties. Something you can easily see and hear. For example on the consistent move of the central second hand.

With the Idea to achieve chronometric accuracy, the beating frequency was raised up to 36000 A/h and spread to different Watch-Series and Qualities. The one shown here is adjusted to 4 Positions.

The Highbeat- Heart brought the disadvantage of higher wear. Nothing that makes a Watchmakers Son afraid ;-) Due to this Problem, Longines reduced the frequency to 28800 A/h later on.

Beautiful Watches are available, equipped with this Movement. Diving Watches as well as Dressers in different shapes and sizes.

The one here appears to be a typical 70ties child. 1968 to be more exact. Thank you to the famous Longines Service helping me with this Information.

Beautiful rectangular, stainless steel case:



Nice stainless steel back with Ultrachron print:

The first Picture is giving a hint on how to open the Watch. The Crown is just to be pulled out. Very clever designed.

Now you have all the Beauty of the 431 Movement in front of you: _ultrachron%20rectangular%2014.jpg

I just got one of 36000 vph Longines. Just want to make sure how does it look? Is it all original? Please feel free to comment. BTW, I did some research that this type of ultra fast moving speed need more lubricating than other lower vph. Any suggestion about time interval for lubrication of this watch, Thanks in advance
